Disease threat: Snake bites
Hazard description: Across tiger range states there are likely to be many species of venomous snake, particularly tropical and sub-tropical areas (Gutiérrez et al. 2006). A search of the literature found just one report of the death of a captive white tiger from a snake bite in the Kamala Nehru Zoo in north-west India (https://www.aol.com/article/2014/12/29/rare-white-tiger-dies-from-snake-bite-in-zoo/21122158/). Tigers may prey on snakes (Hunter 2015) – and thus are at risk of being envenomed by a bite.
Host species: Any.
Pathogenesis: A variety of mechanisms underpin venom toxicity, including the following, alone or in combination, depending on the exact nature of the venom: local tissue necrosis (swelling, blistering etc.), neurotoxicity (paralysis); rhabdomyolysis (leading to myoglobinaemia and renal failure); spontaneous haemorrhage (possibly cerebral); disseminated intravascular coagulation; acute renal failure; and acute respiratory distress. This is not an exhaustive list since the variety of snake venoms is extensive (Gutiérrez et al. 2006).
Diagnosis: Clinical signs.
Vaccination: Not applicable.
Free-ranging tiger occurrence: An anecdotal report of a tiger found dead in the Sundarbans Tiger Reserve in India, that had eaten a King Cobra and an Indian Cobra (Hunter 2015).
